推介了第一本
SRE
书之后，再度受邀为它的续集作序。与第
一本书不同的是，在这本书中作者们不再只是专注于讲述他们的故事，而是试图面
向更广大的受众，分享他们第一手的经验、实例，并给予不拘形式的指导。只需要
稍加辨别，凡是具备一定现代行业眼界的
IT
界人士都会认为这些宽泛的主题似曾相
识。在这本书里，更多的不是技术规范，而是那些面向用户的服务，以及它们的可
靠性目标。我们会发现，在业务实际的发展过程中，人机系统就应运而生了，该系
统的目的是固有的，而非像外来陨石影响一个已知的基础设施那般。所有人机合作
的部分都是它的重点。事实上，这本书的内容可以总结为以下几点：
•
致力于设定清晰的、量化的服务承诺。
•
通过有限的监控指标，持续地觉知上述量化数值。
•
轮值人员随时待命，以保障实现所做出的服务目标承诺，同时避免过度人为干预，
谨防自动化形同虚设。
服务目标承诺是否（对所有相关的各方）能兑现，取决于它所依赖的服务是否稳定、
取决于主观意志和所有参与人员（例如，参见《
Thinking in Promises
》一书）。值得
注意的是，人类对人机系统的看法容易受限于感知的范围，尽管自动化不能完全取
代人类，但它却重新定义了人类所需要的规模，即起源于一个小小的想法，最终成
长为用户遍布全球的大规模系统。

本来就经历了很多个迭代。我们曾经对这些经验教训不断地提出质疑、反复试验
